I see you have found forty White Mandragora Roots. With this, I will make you *Mandragora Essence of the finest quality*. The extra red roots are of no use to you, so may I have them?

Here, take this. It is completed Mandragora Essence. Isn't the essence clear and transparent? It is thicker than regular red essence, and its effects are many times stronger.
